A system and method of limiting power consumption in a telecommunications equipment coupled between a plurality of far end subscriber lines and a plurality of near end subscriber lines are provided. The method includes monitoring and determining a number of ringing subscriber lines, comparing the number of ringing subscriber lines to a predetermined ringing threshold, monitoring and determining a number of off-hook subscriber lines, comparing the number of off-hook subscriber lines to a predetermined off-hook threshold, and blocking further ringing and/or off-hook subscriber lines in response to the number of ringing and/or off-hook subscriber lines reaching or exceeding the respective predetermined ringing and off-hook thresholds.
Legal claims defining the scope of protection, as filed with the USPTO.
1. A method of power limiting call processing in a telecommunications equipment coupled between a plurality of far end subscriber lines and a plurality of near end subscriber lines, comprising: monitoring and determining a number of subscriber lines that are ringing; comparing the number of ringing subscriber lines to a predetermined ringing threshold; blocking further ringing on subscriber lines in response to the number of ringing subscriber lines reaching or exceeding the predetermined ringing threshold; and providing a reorder signal to a blocked ringing far end subscriber line.
2. The method, as set forth in claim 1, further comprising: monitoring and determining a number of subscriber lines that are off-hook; comparing the number of off-hook subscriber lines to a predetermined off-hook threshold; blocking further subscriber lines going off-hook in response to the number of off-hook subscriber lines reaching or exceeding the predetermined off-hook threshold; and not providing a dial tone to a blocked off-hook near end subscriber line.
3. The method, as set forth in claim 2, further comprising blocking both ringing subscriber lines and subscriber lines going off-hook in response to the number of ringing subscriber lines reaching or exceeding the predetermined ringing threshold and the number of off-hook subscriber lines reaching or exceeding the predetermined off-hook threshold.
4. The method, as set forth in claim 2, further comprising blocking both ringing subscriber lines and subscriber lines going off-hook in response to the number of off-hook subscriber lines reaching or exceeding the predetermined off-hook threshold.
5. The method, as set forth in claim 1, wherein providing the reorder signal comprises: providing a first reorder signal for a first predetermined time period; and providing a second reorder signal for a second predetermined time period.
6. The method, as set forth in claim 5, wherein providing the reorder signal comprises: providing the first reorder signal for 2.5 seconds; and providing the second reorder signal for 12.5 seconds.
7. The method, as set forth in claim 5, wherein sending the reorder signal comprises providing an off-hook signal for the first and second predetermined time period.
8. The method, as set forth in claim 5, wherein sending the reorder signal comprises providing an on-hook signal for the first and second predetermined time period.
9. The method, as set forth in claim 5, wherein providing the reorder signal comprises: providing an off-hook signal for the first predetermined time period; and providing an idle signal for the second predetermined time period.
10. The method, as set forth in claim 5, wherein providing the reorder signal comprises: providing an off-hook signal for the first predetermined time period; and providing an on-hook signal for the second predetermined time period.
11. The method, as set forth in claim 1, wherein providing the reorder signal comprises: sending an off-hook signal to the far end subscriber line; sending an on-hook signal to the far end subscriber line after sending the off-hook signal; and providing the reorder signal to the far end subscriber line.
12. An access multiplexing terminal coupled between a central office and a plurality of subscribers, comprising: a first plurality of line cards coupled to a plurality of subscriber lines; a second plurality of line cards; a first plurality of twisted pairs coupling the second plurality of line cards to the central office; a second plurality of twisted pairs coupling the access multiplexing terminal to a network power supply; and a bandwidth allocator monitoring a number of subscriber lines that are ringing and a number of subscriber lines that are off-hook, the bandwidth allocator blocking further ringing and off-hook subscriber lines in response to the numbers thereof exceeding predetermined ringing and off-hook thresholds.
13. A method of limiting power consumption in a telecommunications equipment coupled between a plurality of far end subscriber lines and a plurality of near end subscriber lines, comprising: monitoring and determining a number of subscriber lines that are ringing; comparing the number of ringing subscriber lines to a predetermined ringing threshold; monitoring and determining a number of subscriber lines that are off-hook; comparing the number of off-hook subscriber lines to a predetermined off-hook threshold; blocking further ringing and/or off-hook subscriber lines in response to the number of ringing and/or off-hook subscriber lines reaching or exceeding the respective predetermined ringing and off-hook thresholds.
14. The method, as set forth in claim 13, further comprising providing a reorder signal to a blocked ringing far end subscriber line.
15. The method, as set forth in claim 13, further comprising not providing a dial tone to a blocked off-hook near end-subscriber line.
16. The method, as set forth in claim 13, wherein providing the reorder signal comprises: providing a first reorder signal for a first predetermined time period; and providing a second reorder signal for a second predetermined time period.
17. The method, as set forth in claim 16, wherein providing the reorder signal comprises: providing the first reorder signal for 2.5 seconds; and providing the second reorder signal for 12.5 seconds.
18. The method, as set forth in claim 16, wherein sending the reorder signal comprises providing an off-hook signal for the first and second predetermined time period.
19. The method, as set forth in claim 16, wherein sending the reorder signal comprises providing an on-hook signal for the first and second predetermined time period.
20. The method, as set forth in claim 16, wherein providing the reorder signal comprises: providing an off-hook signal for the first predetermined time period; and providing an idle signal for the second predetermined time period.
21. The method, as set forth in claim 16, wherein providing the reorder signal comprises: providing an off-hook signal for the first predetermined time period; and providing an on-hook signal for the second predetermined time period.
22. The method, as set forth in claim 13, wherein providing the reorder signal comprises: sending an off-hook signal to the far end subscriber line; sending an on-hook signal to the far end subscriber line after sending the off-hook signal; and providing the reorder signal to the far end subscriber line.
